V440-F C-Mount Code Reader User Manual
With Only If All Good Reads enabled, the reader outputs symbol data only
when all symbols in the read cycle are qualified. No Read is output if no
symbols are qualified.
This command allows the user to choose when symbol data can be sent to the
host.

As Soon As Possible
0 = ASAP 1 = End of Read Cycle
As Soon As Possible is useful in applications in which symbol data needs to
be moved quickly to the host, typically when the host is making decisions
based on symbol data.
Enabling As Soon As Possible causes symbol data to be sent to the host
immediately after a symbol has been successfully decoded.
End of Read Cycle is useful in timing-based systems in which the host is not
ready to accept data at the time that it is decoded.
Enabling End of Read Cycle means that symbol data does not get sent to the
host until the read cycle ends with a timeout or new trigger.
